STP

0 degrees and 101 KPa


SATP

25 degrees and 100 KPa


Pressure is....

force per unit area


What are four physical properties of gases?

Always fill their containers
Are highly compressible Diffuse Temperature effects either the volume or the pressure of a gas 

The pressure exerted by air

Atmospheric pressure (1 atm)


________ effects either the volume or pressure of a gas

Temperature


Gases increase in volume and pressure when _______

Heated


At sea level, average atmospheric pressure is about....

101 KPa


What does STP stand for?

Standard temperature and pressure


What does SATP stand for?

Standard ambient temperature and pressure


What is Boyle's Law?

as the pressure on a gas increases, the volume of the gas decreases, other variables such as temperature and amount of gas remain constant.


How can we write out Boyle's Law?

V1P1= V2P2


Convert 20 degrees celcius into Kelvin

293 K


Convert 300K into degrees celcius

27 degrees celsius


What are the temperatures in K of STP and SATP?

STP= 273 K
SATP=298 K 

French physicist Jacques Charles determined the relationship between the ______ and ______ of a gas

temperature and volume


What number do you add to convert degrees celsius to kelvin?

273!!


What does the Charles law state?

The volume (V) increases proportionally as the temperature (T) increases


What is the formula used in the Charles Law?

V1 = V2
  T1 = T2 

True or false
Temperature must be in Kelvin in the Charles Law? 
True


What do you call the Charles and Boyles Law when put together?

The combined gas law


What is the formula for the combined gas law?

p1v1 = p2v2
 T1 T2 

Molar mass is in...

g/mol


How do we calculate the molar mass?

1. Write the correct chemical formula
2.Find the atomic molar mass 3. Add together 

What formula do we use when we need to find the relationship of amount in moles, mass and molar mass?

n= m
 M 

What is the molar volume of a gas at SATP?

24.8 L/Mol


What is the molar volume of a gas at STP?

22.4 L/Mol


Why is it easier to work with volume instead of the mass of a gas?

It is much more convenient because it is more precise, since gases have such small amoounts of mass.


what is the formula for molar volume?

n= v
 V
